CROSS REFERENCE TO RELATED APPLICATIONS

This application relates to, claims priority from and the benefit of co-pending U.S. provisional patent application Ser. No. 62/805,510 entitled REPOSITIONABLE CRANK EXERCISE DEVICE, filed Feb. 14, 2019, the disclosure of which is incorporated herein by reference as if set forth in full.

TECHNICAL FIELD

This disclosure relates generally to exercise apparatuses and more particularly to an exercise apparatus having a repositionable crank.

BACKGROUND

One of the challenges with working out at home is that there are often space challenges as equipment tends to be large and bulky so it can quickly takes up a lot of space in a room. One must only think about the amount of space a Treadmill or a Free Weight Bench takes up to understand this observation. There is an unmet need for a device or apparatus that can be used for a number of exercises. One solution is to rotate a Stationary Bike so it can be used as a hand crank for an upper body cardio workout.

SUMMARY

A Base Unit consists of a repositionable crank system with interchangeable crank drivers that can be used for different exercises using a variety of attachments as seen in FIGS. 1-6. In one position, the Device's Base Unit would support using the attachment for a Spin Bike workout, in another it would use the interchangeable crank driver that can be used as a hand crank for an upper body workout.

Radio Remote for Tension Controller: An exemplary embodiment of a system that includes a base unit of the present invention further include a wireless tension controller. Wireless communication is by any suitable means such as Bluetooth or a plug and play dongle to eliminate the need for Bluetooth pairing.

In other alternative exemplary embodiments, the wireless signal receiving housing will be able to be snapped on and off of the various workout attachments for easy use in the various exercise configurations.

FIG. 8 is a cross section top view of an exemplary alternative embodiment of a spine base unit of the present invention. Base unit 100 is secured in position on platform 120 (not shown) with lock 135. Hinges 820, 822 allow position rail spine member 130 to fold vertically for storage. Spine member 130 is sectional and expandable as indicated with dividing lines 810. A series of locking holes 132 is provided to facilitate securing an attachment in a selected position.

Base Unit Overhead View: An advantage of the spine base embodiment of FIG. 8 is better ease of use for adaptive athletes, particularly so that those who are wheelchair-bound or have other mobility constraints can use the device without needing to transfer out of their chairs.

The spine-based embodiment provides easily incorporated locking/securing holes for the various exercise components. An expandable spine 130 may accommodate future exercise components that have not yet been envisioned. The spine includes hinges 820,822 so that the spine can be raised up, perpendicular to the ground so it takes up less storage space. Also provided is a locking lever 35 to secure the spine in place.

Data, Monitors & Digital Readouts: Specific alternative embodiments of the present exercise apparatus support a smart phone app that is included as an optional component of a system that includes an apparatus of the present invention. A smart shone app helps users to monitor and control their workouts. The app connects to the base unit 100 via Bluetooth or other suitable wireless connection to receive speed and resistance data. The app may be set to automatically adjust tension to keep the exerciser in the optimum heart rate workout zone using data from a heart-rate monitor and personal data (age, sex, weight, etc).

FIG. 9 is an isometric exploded view of an exemplary embodiment of a crank drive of the present invention. Main body 900 provides threaded aperture 910 to threadedly receive a pedal member or pulley crank or other resistance conveying component. Top piece 930 provides protrusion 932 which is shaped to fit into receiving portion 950 of main body 900 and which protrusion 932 has a threaded center hole to receive top cap 920A, 920B.
